Thanks very much for having me before this committee.
Broadly speaking, I think there are two ways in which Canada can address the issue of tax havens. The first is to continue to reduce Canadian corporate taxes to in effect make Canada itself a tax haven. That seems to have been the thrust of Canadian tax policy over the past decade.
The other option, and the one I'm going to be supporting, is that Canada can structure its tax system in a way that collects appropriate corporate tax revenue despite the existence of tax havens offshore.
In particular, I'd like to focus on the issue of interest deductibility, which has become entangled in this debate about tax havens. Yesterday the Government of Canada announced that it would continue to allow corporations, for the most part, to deduct from their Canadian taxes interest on loans to finance their foreign affiliates.
The proposal I would like to put to this committee is that if the government is going to implement that plan, it should also begin taxing the income of foreign affiliates of Canadian corporations.
The basic principle of corporate tax is that it should apply to profit, which is income minus the expenses incurred in generating it.
Prior to the last federal budget, corporate Canada was having its cake and eating it too. It wasn't paying any tax, or was paying almost no tax, on the income of its foreign affiliates, but at the same time it was able to deduct the financing costs of those affiliates from its Canadian taxes.
What budget 2007 proposed to do was to put Canada's corporate tax system on a purely territorial basis, so that Canada would tax income generated in this country and allow the deduction of expenses incurred in generating that income.
The criticism of that budget measure was essentially that Canada needed foreign affiliate interest deductibility in order to be competitive, because other countries had that type of deduction. What critics neglected to mention, of course, was the fact that other countries that allow that deduction, such as the United States, Britain, and Japan, also tax the incomes of the foreign affiliates of their corporations. In other words, they tax corporations on a worldwide basis, including the incomes of foreign affiliates, and allow the deduction of the expenses of those affiliates.
I'd just like to read into the record a quotation from Bruce Bartlett, in his brief analysis of corporate taxes for the National Center for Policy Analysis in the United States. The quote begins:
The United States’ tax system is “worldwide,” requiring domestic companies to pay taxes on income earned abroad. Thus, for example, a territorial company that incorporates in Canada pays taxes only on its operations in Canada. If it has a U.S. subsidiary, the subsidiary pays U.S. taxes on its profits here, but none to Canada. However, due to the U.S. worldwide tax system, the exact same U.S. company with an identical Canadian subsidiary will pay Canadian taxes plus U.S. taxes on its Canadian operations. The U.S. company will pay more total taxes even if the United States and Canada have the same tax rates.
Of course, Canada will now have lower tax rates than the United States. So it seems that we're headed in the direction of becoming a tax haven ourselves.
To put the Canadian corporate tax system back on a consistent basis, what I would propose we need to do is start taxing Canadian corporations on a worldwide basis. That would put them on exactly the same footing as their American, British, and Japanese competitors, where they would be able to deduct the interest costs of setting up these foreign affiliates and then would have to pay Canadian taxes on the incomes of those foreign affiliates.
A final benefit of this plan is that it would guard against tax havens, because Canadian-based companies would be taxed at the Canadian rate on all of their activities in the world. For example, if a Canadian company were to set up a foreign affiliate in Barbados, it would pay the Barbados corporate tax and then would be able to deduct it from the Canadian tax it would pay on those operations. But overall, it would face exactly the same tax rate on its operations in Barbados as on its operations in Canada.
In addition to the fact that I think this just makes rational sense from a theoretical perspective and would put the Canadian tax system on a consistent basis, I also think it would go a great distance towards guarding against tax havens.
Thanks very much.
